If the system uses HANA DB, you can execute the following task lists to adjust the ESH connectors:

After a System Copy -> task list SAP_ESH_ADJUST_AFTER_COPY in client 000 of the target system.
After a Client Copy (within a system) -> task list SAP_ESH_ADJUST_AFTER_CLIENT_COPY in the target client.

This is the preferred method, and it is faster than recreating the connectors from scratch.

However, if those tasks fail in any way, you need to reset ESH and recreate the connectors. That is done this way:

1. Execute task list SAP_ESH_RESET in the working client.

2. Only if you have a SAP_BASIS release between SAP_BASIS 740 and SAP_BASIS 750 SP03 inclusive:
   Execute task list SAP_ESH_INITIAL_SETUP_000_CLIENT in client 000
   How-to: 2626067 - How to execute SAP_ESH_INITIAL_SETUP_000_CLIENT
   
   
3. Execute task list SAP_ESH_INITIAL_SETUP_WRK_CLIENT in the working client

Hello, what if we are using CDS based search, is the procedure the same?

Also do you maybe know if there is any cleanup necessary after move to CDS based search from TREX?

thanks

Also, if the performance of the task lists is poor, refer to these notes:
